Essential Oil of<i>Coleus aromaticus</i>Benth. from India

Abstract

Abstract The essential oils of Coleus aromaticus distilled in different seasons have been analyzed by capillary GC and GC/MS. The oils were found to contain carvacrol (53.0–67.0%), p-cymene (6.5–12.6%) and γ-terpinene (5.9–155%) as major constituents. The oil produced in September was found to contain higher contents of carvacrol and β-caryophyllene and oxygenated constituents than the oil produced in May.
